If you mean is there a higher resolution texture replacer for CI's work then the answer is no
Now for a long answer on how to do it yourself
You can easily replace various robes with other modders work - for instance BadKarma did some beautiful dresses that pass as robes
Try her http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=2874
Or http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=2871
Or http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=5822 for more battlemage type robes
Otherwise you could try http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=6207 which has very good textures for robes
As I said it is not hard to replace the meshes - find the one you want to replace and rename the one you wish to replace it with with the same name - you will also need to do that for the hands versions - switching textures is again not hard - just time consuming
For Hurdy Gurdy's robes - it hasn't been a popular mesh I don't know why I like the reduced bust size it has - anyway there are a few good textures I've used before I have one called Hurdy Gurdy, Lillia & Friends Female robes set 2 but am not sure where I got it from - maybe ElricM - can't see it on PES
